A snap-on assembly includes a housing that holds an integrated circuit with a sensor. A connector supplies power to the integrated circuit and transmits a signal from the integrated circuit to an electronic circuit. An insert fits into an opening of the housing and secures a conductor in the housing without a mechanical fastener. The sensor measures a magnetic field resulting from a current traveling through the conductor.

Snap-on current sensor design

A pyrotechnic current breaker with passive and active triggering for severing a busbar through which electric current flows has a housing through which passes the busbar that is formed with at least one break point and an adjacent fuse part. A separating punch is shiftable in the housing past the busbar to cut same. There is also a first igniter for passive triggering and moving the punch past the busbar and a second igniter for active triggering and moving the punch past the busbar. Both of the igniters act on the separating punch such that, when triggered, the separating punch cuts the busbar at the break point. The first igniter has two conductors connected to two sides of the fuse part and the second igniter has contacts connectable to an external trigger. One of the igniters is in the separating punch.
